8.55. glusterfs

Updated glusterfs packages that fix several bugs and add one enhancement are now available for Red Hat Enterprise Linux 6.

Red Hat Storage is software only, scale-out storage that provides flexible and affordable unstructured data storage for the enterprise. GlusterFS, a key building block of Red Hat Storage, is based on a stackable user-space design and can deliver exceptional performance for diverse workloads. GlusterFS aggregates various storage servers over network interconnects into one large, parallel network file system.

Previously, the "errno" value was not set correctly during an API failure. Consequently, applications using API could behave unpredictably. With this update, the value is set properly during API failures and the applications work as expected.

Previously, the glusterfs-api library handled all signals that were sent to applications using glusterfs-api. As a consequence, glusterfs-api interpreted incorrectly all the the signals that were not used by this library. With this update, glusterfs-api no longer handles the signals that it does not use so that such signals are now interpreted properly.

Previously, the glfs_fini() function did not return NULL, even if the libgfapi library successfully cleaned up all resources. Consequently, an attempt to use the "qemu-img create" command, which used libgfapi, failed. The underlying source code has been modified so that the function returns NULL when the libgfapi cleanup is successful, and the command now works as expected.

Native Support for GlusterFS in QEMU has been included to glusterfs packages. This support allows native access to GlusterFS volumes using the libgfapi library instead of through a locally mounted FUSE file system. This native approach offers considerable performance improvements.

Users of glusterfs are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.
